20 Bus "Time-Fill" Hydrogen Fuel Appliances

Turnkey Systems

Building on proven hydrogen plant designs of The Electrolyser Corporation Ltd., Stuart Energy can supply fully engineered hydrogen vehicle fuel appliances. Appliances include on-site hydrogen production using water electrolysis with storage systems designed to provide the lowest cost hydrogen based on available power rates.

Why Electrolysis

The inherent stability of the Stuart Energy electrolysis process allows operation on an intermittent basis; production can be scheduled to meet fuel demand and low power rates. The electrolysis cell technology of Stuart Energy Systems Inc. has been proven in industrial applications. The production rate is flexible so it can be increased to take advantage of "off-peak" electricity rates and reduced during peak demand periods. Direct refueling by on-site electrolysis reduces the amount of hydrogen fuel storage further enhancing the safety of the system.

Rapid Deployment

In most configurations the fuel appliance can be supplied as a combination of Stuart Energy modules. The modules are built into shipping containers for transportation to site and rapid deployment. The basic system consists of electrolysis production equipment, including power supply and compressors, in one or more containers. Storage, when needed, is provided in standard high pressure gas receivers. Fuel appliances with an output pressure of up to 5000 psig can be provided.

Automatic/Unattended Operation

The fuel appliance is designed to operate unattended and only requires occasional inspection. Monitoring and on-site maintenance can be supplied by Stuart Energy so the fuel appliance operator need only initiate refueling. The modular construction of Stuart Energy plants guarantees production availability even during maintenance periods.
